Embodiment

[0146] In order to illustrate the present invention more clearly, the present invention will be further described below with reference to the preferred embodiments and accompanying drawings. Similar parts in the figures are identified with the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0147] In this example, the Harbin Metro Museum Station is selected as the prototype of the research, and the subway station is modeled according to the actual passenger flow data collected. Combined with the configuration of various facilities in the subway station and their related attributes, the knowledge element is used to analyze the subway station and carry out dynamic evacuation. During the construction of the station knowledge element, the change of passenger flow under emergency conditions and the influence...

Abstract

A dynamic emergency evacuation method for failure of urban rail transit lines relates to the technical field of rail transit control. Solve the problem that the evacuation capacity of a single station is limited, resulting in the secondary spread of the stranded passenger flow in the network. Establish each station attribute set and station operation state set in the network; analyze the station passenger flow state; use SAS software to predict the subway passenger flow in a short time, and simulate the passenger flow arrival process; determine the evacuation starting point and evacuation end point; construct emergency state rail bus coordinated evacuation network; build a path dynamic selection model within the range of the starting and ending points; determine the best evacuation path; determine the required number of emergency buses and the running time interval; determine the distribution law of the passenger flow to be evacuated to the evacuation subway station; The train transportation capacity, combined with the passenger flow of the subway station, allocates resources for the train transportation capacity, and formulates the train operation plan in the emergency state. Increase the passenger flow evacuation capability of a single node and improve the network evacuation efficiency.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to an emergency evacuation method for a rail traffic network. Background technique [0002] As the main public transportation mode for residents to travel, urban rail transit has developed and expanded in various cities. Rail transit lines and stations are no longer separate individuals, but are interconnected as a whole to serve the public. This interrelated feature makes the rail transit network in an emergency, in addition to causing a certain impact on the site where the incident occurs, it will also cause some line services to be interrupted. Ground traffic, resulting in the secondary spread of large passenger flow. Therefore, in addition to focusing on the evacuation in the subway station, the emergency evacuation is also worthy of attention to the further evacuation after the passenger flow arrives outside the station. At the same time, considering the complex ...
